The classic Miller–Urey experiment and similar research demonstrated that most amino acids , the basic chemical constituents of the proteins used in all living organisms, can be synthesized from inorganic compounds under conditions intended to replicate those of the early Earth . Various external sources of energy that may have triggered these reactions have been proposed, including lightning and radiation . Other approaches ("metabolism-first" hypotheses) focus on understanding how catalysis in chemical systems on the early Earth might have provided the precursor molecules necessary for self-replication . [20] Complex organic molecules have been found in the Solar System and in interstellar space , and these molecules may have provided starting material for the development of life on Earth.

A second wave took place after the Toba supereruption ( c. 77,000 years ago) via the so-called Southern Route, following the southern coastline of Asia , which led to the lasting colonization of Australia by around 65,000–50,000 years ago [note 1] [note 2] while Europe was populated by an early offshoot which settled the Near East and Europe less than 55,000 years ago.

She treats the symptoms but also finds the origin/cause of the pain. For example the weakest links will break. She manages to find where the neuromuscular imbalances are that can cause a tissue to break down under mechanical stress.
